xcode9

I am using the latest version of Xcode 9 and macOS 10.13. When I try to make a memory graph from the current state of my application, it shows an empty screen that says No Selection . I also tried to profile and work with Instruments, but it did not allow me to run due to a permission error. Target failed to run. Permission to debug [app name] was denied. I am aware of these threads and tried the suggestions available in them, but they didn't seem to work : Reddit - Has instruments stopped working for you in Xcode 9 due to a permission denied error? Is there a workaround for this? Apple

struct Task: Codable { var content: String var deadline: Date var color: UIColor ... } There are warnings saying "Type 'Task' does not conform to protocol 'Decodable'" and "Type 'Task' does not conform to protocol 'Encodable'". I searched and found that this is because UIColor does not conform to Codable. But I have no idea how to fix that. So... How to make UIColor Codable? If you care only about the 4 color components this is a simple solution using a wrapper struct struct Color : Codable { var red : CGFloat = 0.0, green: CGFloat = 0.0, blue: CGFloat = 0.0, alpha: CGFloat = 0.0 var uiColor :

I´m developing software based on C++ in Xcode and want to have (at least) the same convenience for code documentation as if I was developing for Swift or objc. Example: std::string myString("hello"); if (myString.empty()) { // do something } If I want to know exactly what .empty() does, I would like to Option-Click on the function and get the documentation overlay with information from e.g. http://en.cppreference.com/w/cpp/string/basic_string/empty , exactly as it does for objc and Swift. How is this possible? Current output just looks like this: You cannot. According to Apple's Xcode release

I have checked the question related to how to find the current Swift version by the command swift --version , but how can I upgrade my Swift version from 3.1 to 3.2? (because the Xcode 9 only supports Swift 4.0 & Swift 3.2) To build successfully both in Xcode 8 & Xcode 9, it's better to upgrade Swift from 3.1 to 3.2. But how? My target was to make sure build successfully both in Xcode 8 & Xcode 9, So that publish with Xcode 8 would be OK, and try out the feature of Xcode 9 is OK too. So I will not upgrade code to swift 4.0 yet until Xcode 9.0 official edition is published. After my test, I can

In macOS 10.13 High Sierra on Xcode 9 I get this log message: 2017-09-28 15:19:28.246511+0800 wr[5376:128702] MessageTracer: load_domain_whitelist_search_tree:73: Search tree file's format version number (0) is not supported 2017-09-28 15:19:28.246541+0800 wr[5376:128702] MessageTracer: Falling back to default whitelist What is the meaning of this message? Those messages come from a function msgtracer_domain_new in /usr/lib/libDiagnosticMessagesClient.dylib . Run your application on Xcode 9. Stop it.
