Hi,We've noticed a few cases of a cpu_resource_fatal crash report for our app. The logs for the crash are somewhat interesting but don't really provide an obvious path forward to identifying the root cause or fixing the issue. I've been searching for a while to find some sort of documentation on this but I haven't found anything conclusive. The only thing I've found that really even hints at this issue is:https://developer.apple.com/library/archive/documentation/Performance/Conceptual/EnergyGuide-iOS/WorkLessInTheBackground.html"iOS employs a CPU Monitor that watches background apps for excessive CPU usage and terminates them if they fall outside of certain limits. Most apps performing normal background activity should never encounter this situation. However, if your app reaches the limits and is terminated, the crash log indicates the reason for the termination. An exception type of EXC_RESOURCE and subtype of CPU_FATAL is specified, along with a message indicating that limits were exceeded. See Listing 3-6."Our crash log doesn't have an exception type though. This is what it looks like below.I'm really struggling to figure out what would cause this. Is this caused by some sort of deadlock? Or by a runaway computational process? Or by a leaked background task?I have two sysdiagnose logs from when this has happened, but haven't found anything compelling in either of them yet.Any help is appreciated. Thanks!- Conrad{"app_name":"MapMyRun","timestamp":"2018-09-22 08:59:45.18 -0500","app_version":"18.8.5_beta_670e","slice_uuid":"A7173537-ED4B-3677-9893-4C882D0EB93A","adam_id":0,"build_version":"1809212128","bundleID":"com.mapmyfitness.MapMyRun","share_with_app_devs":false,"is_first_party":false,"bug_type":"206","os_version":"iPhone OS 11.4.1 (15G77)","incident_id":"26C70EF6-4844-4EC0-82B5-8F0D64022375","name":"MapMyRun"} Date/Time: 2018-09-22 08:58:50.113113 -0500 OS Version: iPhone OS 11.4.1 (Build 15G77) Architecture: arm64 Report Version: 19 Command: MapMyRun Path: /private/var/containers/Bundle/Application/B76F8244-CE8E-468E-9073-A2DFAA089DEB/MapMyRun.app/MapMyRun Version: 18.8.5_beta_670e (1809212128) Beta Identifier: 2FFE057C-B975-449C-B538-08A1D58CD510 PID: 2489 Event: cpu usage Action taken: Process killed CPU: 48 seconds cpu time over 54 seconds (88% cpu average), exceeding limit of 80% cpu over 60 seconds CPU limit: 48s Limit duration: 60s CPU used: 48s Duration: 54.45s Steps: 15 Hardware model: iPhone9,3 Active cpus: 2 Powerstats for: MapMyRun [2489] UUID: A7173537-ED4B-3677-9893-4C882D0EB93A Start time: 2018-09-22 08:59:29 -0500 End time: 2018-09-22 08:59:44 -0500 Microstackshots: 15 samples (100%) Primary state: 11 samples Frontmost App, User mode, Effective Thread QoS Background, Requested Thread QoS User Interactive, Override Thread QoS Unspecified User Activity: 15 samples Idle, 0 samples Active Power Source: 15 samples on Battery, 0 samples on AC 11 ???

I'm using the setShortcutSuggestions method to add several NSUserActivity-based siri shortcuts to appear as options in the Shortcuts app. Previously this used to work fine and all of my suggestions appeared as options in the Shortcuts app. Now on the latest version of iOS and the Xcode 11.5 SDK this method no longer appears to be working for me, or I'm doing something wrong. Is there something else I should check if none of the shortcuts I'm providing are surfaced as options in the shortcuts app? I am setting isEligibleForPrediction to true on the user activity object when I create it.

We're trying to use the HKWorkoutConfiguration API to launch our watch app from the parent iPhone app, but we seem to be getting this error a lot. We're trying to understand what it means and what we can do about it. Whenever it happens, the watch app fails to launch when we start a workout on the iOS counterpart app.There was an issue starting the workout via HKWorkoutConfiguration(). Error: Error Domain=com.apple.healthkit Code=550 "Unable to launch watch app" UserInfo={NSLocalizedDescription=Unable to launch watch app} ||

I'm seeing very strange behavior with the input accessory view in multi window on iPad in iOS 13. The first view that gets created in a new window receives its input accessory view normally, but all future views in that window do not. Despite calling reloadInputViews, the views never seem to request their accessoryInputView and the accessoryInputView is never added to the text input window. As a result - input accessory views seem to be pretty broken in multi window on iPad in iOS 13. I'm wondering if anyone else has seen this or knows of a workaround?

I'm using the setAlternateIconName API in iOS 13 and running into a weird issue. The API works, and successfully changes the icon, but the resulting alert view that pops up has no content. I'm wondering how that could be possible and if other people have seen this.

I'm seeing a crash when I attempt to create a new reminder. The crash is in Beta 5 of Xcode 11 / iOS 13.

Hi,If you have already paired with an accessory on iOS, do you need to repeat the pairing process on watchOS in order to connect to an accessory on Apple Watch? Is there any documentation or references to how this should work?Thanks!
