Problems using AdobeMobileSDK under iOS 11

[Former Community Member]

Hi,

I've received issue from iOS developing team working with beta version of newest Apple system, as follows:

We run  collectLifecycleData just after application starts:

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        #if DEBUG

ADBMobile.setDebugLogging(true)

        #endif

        ADBMobile.overrideConfigPath(Bundle(for: object_getClass(self)).path(forResource: "ADBMobileConfig", ofType: "json"));

ADBMobile.collectLifecycleData()

initializeServices()

on iOS 11 there's an Adobe crash in log:

=================================================================

Main Thread Checker: UI API called on a background thread: -[UIApplication applicationState]

We suppose the reason: iOS11 not allow run UI function in background thread. We know that is sometimes strange mean "UI function" f.ex function like Appdelegate.sharedInstance is for apple UI function.

We use AdobeMobileSDK (4.13.5) from CocoaPods.

Thanks in advance,

Michał

Hi mtrybus_bsk​,

I believe that this issue needs a more secure channel to proceed with analysis as we need to share the below details:

- App Build using which the crash can be replicated

- Adobe Debug Logs (in console logs)

- Code files

Hence, I would suggest one of the Supported Users in your organization to raise a ticket with Adobe ClientCare <clientcare@adobe.com>

Hi!

In message from mtrybus_bsk 2017-08-07 03:10 you have a code snippet and Adobe Debug Logs,

this is all who you need to reproduce and debug a problem. Just connect Adobe library to sample project and add that line: ADBMobile.collectLifecycleData() to didFinishLaunchingWithOptions event.
