After updating Trail Wallet to Swift 3, I started getting crash reports from devices still running iOS 8 and iOS 9. Unfortunately, they were super unhelpful crash reports like this:
Crashed: UIDocument File Access EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x000000005e30c493
Trail Wallet reached 100,000 downloads this week, just shy of its fourth birthday.
