My buddy Dan showed me this cool trick for two finger zooming on the mac.

Open Accessibility in Preferences and select Zoom, then Use scroll gesture with modifier.

Now when you see something you want to zoom into on the screen, hold down control, x2 finger swipe up, and move the mouse around and you will zoom!

Cool. Thx Dan.

Trouble Installing Link Conditioner

1 Comment

With the latest Mojave upgrade, Link Conditioner wasn’t installing correctly. You would follow instructions that would normally work like this

Only do have it disappear in the System Preferences after using it once.

My buddy Dan showed me the fix. First remove the link conditioner from your personally library preference pane like this

cd Library/PreferencePanes
rm -rf Network\ Link\ Conditioner.prefPane

Then manually install it in the machine preference by doing this

open /Library/PreferencePanes

And then manually dragging the icon from the Xcode package you downloaded

Into the preference pain you just opened

Once done, the conditioner should show up/and stay in your System Preferences.

Add accessibility to your buttons and controls like this

    let button: UIButton = {
        let button = UIButton()
        button.translatesAutoresizingMaskIntoConstraints = false
        button.backgroundColor = .green
        button.setTitle("GOT IT", for: .normal)
        button.setTitleColor(.black, for: .normal)
        button.addTarget(self, action: #selector(buttonPressed), for: .touchUpInside)

        button.accessibilityIdentifier = "gotItButton"

        return button

Sample test

    func testExample() {
        // Use recording to get started writing UI tests.
        // Use XCTAssert and related functions to verify your tests produce the correct results.

        XCUIApplication().buttons["GOT IT"].tap()
        XCTAssertTrue(XCUIApplication().buttons["gotItButton"].waitForExistence(timeout: 10))

Save this (i.e. svg2pdf). Then find a svg file in your finder and convert it by right clicking on it. You will now have a pdf output into that directory.

Import into Xcode

Xcode will now scale pdfs to various resolutions. To use a pdf as an image asset drag it into your assets folder and make the following changes on the image in the inspector.
