Bugfender is a cloud service to collect mobile application logs. Developers can control log sending programmatically and manually for each device. Logs are available at the Bugfender dashboard. You'll need an account.
Supported iOS versions:
First of all you will need to add the framework to your project.
pod init
pod 'BugfenderSDK', '~> 1.12'
pod install
. This creates an .xcworkspace
file for your app. Use this file for all future development on your application.In Xcode go to the target's General
tab and press on the icon to add a new library
In the popover choose Add Other
and then Add Package Dependency...

as well.There is a known issue in Xcode12 failing to launch apps in a physical device when debugging. At the moment of writing this docs, the issue is still not fixed in Xcode12.3 Beta. The issue should not affect release or simulator versions. But, if you get a No code signature found
or A valid provisioning profile for this executable was not found
we recommend to use the workaround proposed by the PSPDFKit team.

If you are uising CocoaPods the script is already distributed with the Pod from version 1.10.4
If you are using any other installation method you can download the script and copy it into a location inside your project.
For that we need to create a new Run Script on our Build Phases following this steps:
+
sign and select New Run Script Phase.${PODS_ROOT}/BugfenderSDK/upload-symbols.sh <bugfender_symbolication_token>
<path_to_the_script>/upload-symbols.sh <bugfender_symbolication_token>
BUGFENDER_SYMBOLICATION_TOKEN
environment variable.Once you have the framework in your project, using it is as easy as using BFLog()
instead of NSLog()
or bfprint()
instead print()
.
If your application uses SwiftUI and doesn't have an AppDelegate, you might need to create one like this:
@main
struct YourAppNameApp: App {
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
// your Bugfender init code here
return true
}
}
In your AppDelegate class:
@_exported import BugfenderSDK
And add the following to application(_:didFinishLaunchingWithOptions:)
:
Bugfender.activateLogger("YOUR_APP_KEY")
Bugfender.enableUIEventLogging() // optional, log user interactions automatically
Bugfender.enableCrashReporting() // optional, log crashes automatically
bfprint("Hello world!") // use bfprint() as you would use print()
Then you may use BFLog
as you would normally use NSLog
or print
.
You may also want to specify a logging level by using the following helper functions:
Bugfender.print(...)
: Default log.Bugfender.warning(...)
: Warning log.Bugfender.error(...)
: Error log.Make Bugfender available project-wide by adding the following line to the .pch
file:
#import <BugfenderSDK/BugfenderSDK.h>
Get an API key from the Bugfender console. In your AppDelegate
call activateLogger when the application starts, like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
// Activate the remote logger with an App Key.
[Bugfender activateLogger:@"YOUR_APP_KEY"];
[Bugfender enableUIEventLogging]; // optional, log user interactions automatically
[Bugfender enableCrashReporting]; // optional, log crashes automatically
BFLog("Hello world!") // use BFLog as you would use NSLog
...
}
Then you may use BFLog
as you would normally use NSLog
.
You may also want to specify a logging level by using the following macros:
BFLog(...)
: Default log.BFLogWarn(...)
: Warning log.BFLogErr(...)
: Error log.Bugfender allows you to send issues to the server. An issue is similar to a session but they are showed in the issues
section and you can send issues any time from the app, even if the device is not enabled in the system. Issues are useful to keep track of important errors that you can detect in your code.
For sending an issue you can use the following function:
Bugfender.sendIssueReturningUrl(withTitle: "Issue title", text: "Description of the issue")
Nothice that text
supports Markdown notation on the server. You can add some style to the text.
Bugfender.sendIssueReturningUrl(withTitle: "App Error", text: "We have found an **Error**, we need to check it")
Send issue returns an URL pointing to the issue in the Dashboard of Bugfender. You can use that URL to create automations.
In some special circumstances you may want to send logs, regardless of the enabled state of the device in the Bugfender console, for example in a custom exception handler. Use forceSendOnce
to force sending the logs once, and use setForceEnabled:
to force it for some period of time.
You can associate information to a device as if it were a dictionary:
Bugfender.setDeviceString("value", forKey: "key")
You can find more information in our blog post Associated device information.
Bugfender keeps up to 5 MB worth of log data in the device. This way Bugfender can work offline, and you can get some log data from the past when enabling a device. You can change that limit with setMaximumLocalStorageSize
.
// Setting maximum cache size to 1 Mb
Bugfender.setMaximumLocalStorageSize(1024*1024)
Sometimes you want to integrate Bugfender with a third party tool. For this purpose, the SDK provides a method that returns the URL for the current device. You can send it to the third party tool and easily navigate back to the logs of the device from the other tool.
Bugfender.deviceIdentifierUrl();
Sometimes you want to integrate Bugfender with a third party tool. For this purpose, the SDK provides a method that returns the URL for the session. You can send it to the third party tool to easily go to the logs of the current session from the other tool.
Bugfender.sessionIdentifierUrl();
Getting feedback from the final users is one of the most important things for an app developer. Good user feedback allows you detect errors in your app and helps you to understand better your product.
Starting from version 1.6, Bugfender provides a new feature to easily collect app feedback from final users. It takes only two minutes and a few lines of code to integrate. You can think about the User Feedback as a special kind of Issue, every time your users submit their feedback you will get a new issue in Bugfender.
The easiest way to implement Bugfender User Feedback is using the customizable User Feedback View Controller. It provides a convenient view controller with two text fields, one short for the subject and another bigger for the feedback. Both text fields grow autommatically.
Using the convenient UI provided by Bugfender requires only creating a new View Controller and presenting it modally. All you need is to call the following method and complete the required parameters with the title and placeholders for your UI.
// Instantiate new User Feedback
let nvc = Bugfender.userFeedbackViewController(withTitle: "Navigation bar title",
hint: "Give some instructions to your users",
subjectPlaceholder: "Placeholder for subject textfield",
messagePlaceholder: "Placeholder for message textfield",
sendButtonTitle: "Send",
cancelButtonTitle: "Cancel") { (feedbackSent, url) in
if (feedbackSent) {
// Say thanks!
// url is a direct link to the dashboard
// Use it to create automations or send it to your server
} else {
// User decided to not send feedback
}
}
// Present modally
self.present(nvc, animated: true, completion: nil)
Additionally, if you require more customization you can configure the view controller prior to presenting it.
Please note BFUserFeedbackNavigationController is a subclass of navigation controller. You need to access the view controller using the public property feedbackViewController.
// Access the root view controller.
let feedbackViewController: BFUserFeedbackViewController = nvc.feedbackViewController
// Change the background colors
feedbackViewController.mainBackgroundColor = UIColor.lightGray
feedbackViewController.secondaryBackgroundColor = UIColor.white
// Change the font of the hint text
feedbackViewController.hintFont = UIFont(name: "Avenir", size: 14)!
For a complete list of customizable attributes you can inspect "BFUserFeedbackViewController.h" or read the docs.
Here is an example using the BFUserFeedbackNavigationController
in SwiftUI:
struct SwiftUIView: View {
@State private var showFeedbackScreen = false
var body: some View {
VStack {
Text("Hello World!")
Button("Show Feedback screen") {
showFeedbackScreen = true
}
}.sheet(isPresented: $showFeedbackScreen) {
FeedbackView() { sent, feedbackUrl in
if sent == true,
let url = feedbackUrl{
BFLog("Sent feedback to URL: \(url.absoluteString)")
} else {
BFLog("User rejected to send feedback")
}
}
}.navigationBarTitle(Text("Swift UI Test"))
}
}
struct SwiftUIView_Previews: PreviewProvider {
static var previews: some View {
SwiftUIView()
}
}
struct FeedbackView: UIViewControllerRepresentable {
typealias UIViewControllerType = BFUserFeedbackNavigationController
let completion: (_ feedbackSent: Bool, _ feedbackUrl: URL?) -> Void
func makeUIViewController(context: Context) -> BFUserFeedbackNavigationController {
BFUserFeedbackNavigationController.userFeedbackViewController(
withTitle: "This title",
hint: "This hint",
subjectPlaceholder: "This subject",
messagePlaceholder: "This message",
sendButtonTitle: "Send",
cancelButtonTitle: "Cancel") { sent, feedbackUrl in
completion(sent, feedbackUrl)
}
}
func updateUIViewController(_ uiViewController: BFUserFeedbackNavigationController, context: Context) {}
}
If you need further customization than provided by BFUserFeedbackViewController you can implement your own UI. All you have to do is collect your user feedback as you wish and send it to Bugfender using sendUserFeedback
:
let feedbackUrl = Bugfender.sendUserFeedbackReturningUrl(withSubject: "Title of the feedback", message: "message of the feedback")
The returned URL is a direct link to the Bugfender's dashboard. Use it to create automations or to keep a reference in your servers.
BugfenderSDK is now a dynamic framework and you will need to check the "embed framework" option when adding it to your project manually or using Carthage.
Additionally, the Bugfender.swift helper class is not needed anymore and can be safely deleted, however, Swift must be available in your project. If you are installing Bugfender manually or using Carthage ensure that Build Settings -> Always Embed Swift Standard Libraries is set to YES.
