How to access bookmark url in macOS

Issue #624

By default the approaches above grant you access while the app remains open. When you quit the app, any folder access you had is lost.

To gain persistent access to a folder even on subsequent launches, we’ll have to take advantage of a system called Security-Scoped Bookmarks.

Add entitlements

Use of app-scoped bookmarks and URLs

3
4
<key>com.apple.security.files.user-selected.read-only</key>
<true/>
<key>com.apple.security.files.bookmarks.app-scope</key>
<true/>

Enabling Security-Scoped Bookmark and URL Access

If you want to provide your sandboxed app with persistent access to file system resources, you must enable security-scoped bookmark and URL access. Security-scoped bookmarks are available starting in macOS v10.7.3.

To add the bookmarks.app-scope or bookmarks.document-scope entitlement, edit the target’s .entitlements property list file using the Xcode property list editor. Use the entitlement keys shown in Table 4-4, depending on which type of access you want. Use a value of for each entitlement you want to enable. You can enable either or both entitlements.

How to present NSWindow modally

Issue #612

Use runModal

This method runs a modal event loop for the specified window synchronously. It displays the specified window, makes it key, starts the run loop, and processes events for that window. (You do not need to show the window yourself.) While the app is in that loop, it does not respond to any other events (including mouse, keyboard, or window-close events) unless they are associated with the window. It also does not perform any tasks (such as firing timers) that are not associated with the modal run loop. In other words, this method consumes only enough CPU time to process events and dispatch them to the action methods associated with the modal window.

NSTextField and NSText

https://stackoverflow.com/questions/25692122/how-to-detect-when-nstextfield-has-the-focus-or-is-its-content-selected-cocoa

When you clicked on search field, search field become first responder once, but NSText will be prepared sometime somewhere later, and the focus will be moved to the NSText.

I found out that when NSText is prepared, it is set to self.currentEditor() . The problem is that when becomeFirstResponder()’s call, self.currentEditor() hasn’t set yet. So becomeFirstResponder() is not the method to detect it’s focus.

On the other hand, when focus is moved to NSText, text field’s resignFirstResponder() is called, and you know what? self.currentEditor() has set. So, this is the moment to tell it’s delegate that that text field got focused

Use NSTextView

Any time you want to customize NSTextField, use NSTextView instead

How to make TextView in SwiftUI for macOS

        Bundle.main.loadNibNamed("ScrollableTextView", owner: nil, topLevelObjects: &views)
        let scrollableTextView = views!.compactMap({ $0 as? ScrollableTextView }).first!
        scrollableTextView.textView.delegate = context.coordinator
        return scrollableTextView
    }

    func updateNSView(_ nsView: ScrollableTextView, context: Context) {
        guard nsView.textView.string != text else { return }
        nsView.textView.string = text
    }

    class Coordinator: NSObject, NSTextViewDelegate {
        let parent: TextView

        init(_ textView: TextView) {
            self.parent = textView
        }

        func textDidChange(_ notification: Notification) {
            guard let textView = notification.object as? NSTextView else { return }
            self.parent.text = textView.string
        }
    }
}

There seems to be a bug that if we have open and close curly braces, any character typed into NSTextView will move the cursor to the end. This is easily fixed with a check in updateNSView

How to handle radio group for NSButton

Issue #579

Use same action, or we can roll our own implementation

An NSButton configured as a radio button (with the -buttonType set to NSRadioButton), will now operate in a radio button group for applications linked on 10.8 and later. To have the button work in a radio group, use the same -action for each NSButton instance, and have the same superview for each button. When these conditions are met, checking one button (by changing the -state to 1), will uncheck all other buttons (by setting their -state to 0).

How to make Swift Package Manager package for multiple platforms

Issue #504

https://twitter.com/NeoNacho/status/1181245484867801088?s=20

There’s no way to have platform specific sources or targets today, so you’ll have to take a different approach. I would recommend wrapping all OS specific files in #if os and just having one target. For tests, you could do something similar, one test target, but conditional tests

Every files are in Sources folder, so we can use platform and version checks. For example Omnia is a Swift Package Manager that supports iOS, tvOS, watchOS, macOS and Catalyst.

For macOS only code, need to check for AppKit and Catalyst

https://github.com/onmyway133/Omnia/blob/master/Sources/macOS/ClickedCollectionView.swift

1
#if canImport(AppKit) && !targetEnvironment(macCatalyst)

For SwiftUI feature, need to check for iOS 13 and macOS 10.15

FIRAnalyticsConnector: building for Mac Catalyst, but linking in object file built for iOS Simulator

https://stackoverflow.com/questions/57666155/firanalyticsconnector-building-for-mac-catalyst-but-linking-in-object-file-bui

The problem was related to the difference between Firebase/Core and FirebaseCore. The first is a subspec of the Firebase pod that depends on FirebaseAnalytics. The second is only the FirebaseCore pod. Only the latter should be used for macOS.
