Problem with In house app upgrade

Issue found in iOS 11 beta 4 :


While upgrading the In house application using OTA link, getting an alert *** wants to install application with options Ok & Cancel . When clicked on OK , the update never happens. Got the error log as seen below :


Jul 31 13:24:48 iPad-Air installcoordinationd(AssertionServices)[175] <Notice>: Failed to acquire termination assertion for event <BKSTerminationAssertionCreateEvent: 0x102007d90; Identifier: 175-14BBBCB9-3BC4-44FC-9C20-37694CC1DB60; Name: FBSApplicationTerminationAssertion; Target BundleID: com.***.***.xxxx; Efficacy: Unused> due to reason: Termination assertion forbidden for foreground process


Going by the log , tried to minimize the app as soon as clicked on the OK in the upgrade alert. And could see that the installation did happen in this case. So it seems that the installation is prevented when the same app is in foreground.


This issue is found in iOS 11 beta 4 and the upgrade works fine in the iOS 10 version. Is this gonna be a feature in iOS 11 or a bug in the current beta version .



Any similar issues found ?

I've also run into this issue with iOS 11 beta 4.

I'm hoping this is a bug that will be fixed and not a new feature, since it would make upgrades more difficult.

Having the similar issue in iOS 11 beta 5 as well. Unable to Download App is being prompted if the app is in foreground.

Still seeing this in iOS 11 beta 6 as well

The behaviour is different in iOS11 beta 6. Instead of prompting Unable to Download App, it is waiting for the app to be put in background after selecting Install. Installation will only start after that.

Even in iOS 11 beta 9 we are seeing the issue, wont we get any response from apple regarding this ??

We are also experiencing this issue when attempting to self update our app. The prompt is shown asking to install the app but after update is clicked nothing happens. Once the app is closed with the home button then the update begins.

Have same problem in iOS 11.1.2 😟
