My company purchased a 1 min looping video from Pond5 in this format: "1920x1080 @25fps / mov / 224.8MB / H.264". The video isn't really a minute long: the first 30 seconds are an animated object, and the last 30 are the an "alpha mask" (white and black image, white the animation object).   When I use AVPlayer to loop the first 30 seconds, the… (Show more)

My current company is hesitant about replacing a piece of code that opens a user-specified URL in Safari with SFSafariViewController. The concern is that our app will need to be more lenient with ATS. My understanding is that any URL that opens with Safari will open in a SFSafariViewController with no change to the app ATS specs.   That said, I… (Show more)
