抓取View Hierarchy，XCode 8.2.1时出错：“没有用于获取视图层次结构的plist数据”

Question

While trying to debug my view hierarchy, I get the following error:

Error:    Unable to capture view hierarchy.
Details:  No plist data for fetching view hierarchy: error evaluating expression “(id)[(Class)objc_getClass("DBGViewDebuggerSupport_iOS") fetchViewHierarchyWithOptions:(id)[(Class)objc_getClass("NSDictionary") dictionaryWithObjects:(id)[(id)[(id)[(Class)objc_getClass("NSArray") arrayWithObject:(id)[(Class)objc_getClass("NSNumber") numberWithBool:1]] arrayByAddingObject:(id)[(id)[(Class)objc_getClass("NSArray") arrayWithObject:@"_UIVisualEffectBackdropView"] arrayByAddingObject:@"_UIBackdropEffectView"]] arrayByAddingObject:(id)[(Class)objc_getClass("NSNumber") numberWithBool:0]] forKeys:(id)[(id)[(id)[(Class)objc_getClass("NSArray") arrayWithObject:@"DBGViewDebuggerUseLayersAsSnapshots"] arrayByAddingObject:@"DBGViewDebuggerEffectViewsToSnapshotAsImage"] arrayByAddingObject:@"DBGViewDebuggerAlwaysEncodeLayers"]]]”: error: Expression can't be run, because there is no JIT compiled function

Occured on iPhone 6 10.2 and iPhone 5C 9.3.5. XCode is 8.2.1. The Mac machine is Sierra 10.12.2 (16C67).

Reproducible always - never got it to work.

Anyone got a clue?

Answer 1

This occurred for me when running on simulator with Xcode 8.0. I was able to eliminate the bug by running on my iPhone 7 (device) running iOS 10.2.

Probably not the answer you want to hear, but you could try downloading Xcode 8.0 at the Apple Developer downloads page.
