I wrote in my iOS 12.2 review that the new Wallet changes felt unfinished, and I was right. The constant Wallet UI tweaking of iOS 12.2 continues unabated in iOS 12.3 beta 4 Apple Pay Suica. The biggest changes are the elimination of separate info and transaction screens. All transaction are now on the main screen, and good old blue highlights are back on the card itself, but Wallet still retains the black theme. It still feels unfinished with more tweaks to come. Here are comparison screenshots.
Transaction details now show location details again, as they did up until iOS 12.2 beta 3, but 3D Touch is missing for ‘pop-up’ transaction details, and transactions cannot be swipe deleted like they can in iOS 12.2 (though they can still be swipe deleted in the Suica transaction list in Settings> Wallet> Suica, what gives?). Icon colors are less garish but only come in 2 varieties: transit and everything else. It would make more sense, and be much more helpful, to have at least one more color to distinguish between transit, purchase and recharge.
This constant hit and miss tweaking is very weird for Apple, almost as if the iOS 13 beta process started with Wallet in iOS 12.2. But I think it has more to do with the unfinished state of Apple Card and the new Wallet UI card design that Apple will probably announce for iOS 13. If nothing else it certainly suggests that the Apple Card UI is a rush job for a product that was pre-announced too soon.
