Hello erichoracek, I ran the demo (DynamicThemingExample) on iPhone5s(iOS 12.2),I see lots of memory leaks. Examples of excerpts are as follows：

0 libsystem_malloc.dylib calloc 1 libobjc.A.dylib cache_t::reallocate(unsigned int, unsigned int) 2 libobjc.A.dylib cache_fill 3 libobjc.A.dylib lookUpImpOrForward 4 libobjc.A.dylib _objc_msgSend_uncached 5 Motif -[MTFThemeClass applyTo:error:] /data/UIDemos/Motif/Motif/Core/MTFThemeClass.m:188 6 Motif -[MTFTheme applyClassWithName:to:error:] /data/UIDemos/Motif/Motif/Core/MTFTheme.m:162 7 Motif -[MTFDynamicThemeApplier applyClassWithName:to:error:] /data/UIDemos/Motif/Motif/Core/MTFDynamicThemeApplier.m:78 8 Motif -[MTFDynamicThemeApplier applyTheme:toApplicants:error:] /data/UIDemos/Motif/Motif/Core/MTFDynamicThemeApplier.m:59 9 Motif -[MTFDynamicThemeApplier setTheme:error:] /data/UIDemos/Motif/Motif/Core/MTFDynamicThemeApplier.m:47 10 DynamicThemingExample -[AppDelegate toggleTheme] /data/UIDemos/Motif/Examples/DynamicThemingExample/AppDelegate.m:137 11 UIKitCore -[UIApplication sendAction:to:from:forEvent:] 12 UIKitCore 45-[_UIButtonBarTargetAction _invoke:forEvent:]_block_invoke 13 UIKitCore -[_UIButtonBarTargetAction _invoke:forEvent:] 14 UIKitCore -[UIApplication sendAction:to:from:forEvent:] 15 UIKitCore -[UIControl sendAction:to:forEvent:] 16 UIKitCore -[UIControl _sendActionsForEvents:withEvent:] 17 UIKitCore -[UIControl touchesEnded:withEvent:] 18 UIKitCore -[UIWindow _sendTouchesForEvent:] 19 UIKitCore -[UIWindow sendEvent:] 20 UIKitCore -[UIApplication sendEvent:] 21 UIKitCore dispatchPreprocessedEventFromEventQueue 22 UIKitCore handleEventQueueInternal 23 UIKitCore handleHIDEventFetcherDrain 24 CoreFoundation CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION 25 CoreFoundation CFRunLoopDoSource0 26 CoreFoundation CFRunLoopDoSources0 27 CoreFoundation __CFRunLoopRun 28 CoreFoundation CFRunLoopRunSpecific 29 GraphicsServices GSEventRunModal 30 UIKitCore UIApplicationMain 31 DynamicThemingExample main /data/UIDemos/Motif/Examples/DynamicThemingExample/main.m:14 32 libdyld.dylib start

PS:I tested on iOS simulator, there is no memory leak on iOS 11.0.1 and iOS 12.0. The iOS simulator12.2 also has memory leaks.
