After updating to Xcode 9, using Swift 3 and the iPhone X simulator, my console is full of: TIC Read Status [11:0x0]: 1:57 TIC Read Status [11:0x0]: 1:57 TIC Read Status [11:0x0]: 1:57 ... What is that and how do I fix it? Help is very appreciated. PS: I prefer not to just "silence" it with an Environment Variable in the build scheme. Apple staff gave the following answer: TIC expands to “TCP I/O connection”, which is a subsystem within CFNetwork that runs a TCP connection 1 and 57 are the CFStreamError domain and code, respectively; a domain of 1 is kCFStreamErrorDomainPOSIX and, within that

The iPad-simulator is really small (like one third the size of the real iPad screen) on my 23" Full-HD screen (and also on the 15" MacBook Pro ). Is there a way to resize it? I know it must maintain size and dpi-ratio to prevent sub-pixels, but I can hardly see anything withoout a magnifier. ⌘ + 1 for 100% ⌘ + 2 for 75% ⌘ + 3 for 50% Xcode 9.x : Select Simulator Goto Window tab Select Physical Size option ( cmd + 1 ) Now if this dosen’t make size as per your interest then follow below steps : Select Simulator Goto edge of simulator . This will convert your cursor to resize option

Wireless debugging was recently added as a feature in Xcode 9, iOS 11, and tvOS 11. Apple TV 4K doesn't have a USB port, so it requires wireless debugging. How do you perform this wireless debugging in Xcode? Set up a device for network debugging from help.apple.com NOTE: Mac system and iPhone/iPad should share same network to use wireless debugging. Debug your app running on an iOS or tvOS device over a WiFi or other network connection. Note: Network debugging requires Xcode 9.0 or later running on macOS 10.12.4 or later , and on the device, requires iOS 11.0 or later , or tvOS 11.0 or later

Codable seems a very exciting feature. But I wonder how we can use it in Core Data? In particular, is it possible to directly encode/decode a JSON from/to a NSManagedObject? I tried a very simple example: and defined Foo myself: import CoreData @objc(Foo) public class Foo: NSManagedObject, Codable {} But when using it like this: let json = """ { "name": "foo", "bars": [{ "name": "bar1", }], [{ "name": "bar2" }] } """.data(using: .utf8)! let decoder = JSONDecoder() let foo = try! decoder.decode(Foo.self, from: json) print(foo) The compiler failed with this errror: super.init isn't called on all
