+- fixed Swift naming collision (due to the Obj-C interface that offers multiple variants of the same method but with mixed and missing params) #1797 fixes #1764
+- coding style #1971
+- fixed Umbrella header warning for the FLAnimatedImage (while using Carthage) d9f7cf4 (replaces #1781) fixes #1776
