Xcode, iOS app debug to device failed due to incompatibility issue

You might see this error message when debugging the app to your device.

This operation can fail if the version of the OS on the device is incompatible with the installed version of Xcode.

Today I would like to share with you how I solved this issue.

Xcode show “Failed to prepare device for development.” error handling -  彼得潘的Swift iOS App 開發教室- Medium

Firstly , you have to check the compatibility versions between Xcode and iOS. You can check on the link below.

https://developer.apple.com/support/xcode/

Secondly , check the version of your iOS device. Let’s say 15.4 in this case. Then you can check the device supports on your Mac. You can check under this path

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/

If the directory is missing download support files for 15.4 (your iOS version) , you can download the files from this github.

As a final step, restart your Xcode.

macOS Montereyがリリースされました

10月26日からmacOS Montereyの配信が開始されました。



FacetimeにWindowsから参加できるようになったり、
写真内のテキストを抽出したり、さらにそのテキストを翻訳できるようになったようです。

私が気になっているのは
Object Capture
というものでコレは複数枚の連続した画像から3Dオブジェクトをつくれるという機能のようです。

追加された機能のうちいくつかはApple Siliconを搭載したmacでのみ利用でき、
Intel CPUを搭載したMacでは利用できないようです。

macとiPadの間をシームレスに操作できるユニバーサルコントロール機能は、
リリース時には含まれず、秋ごろのアップデートで追加されるそうです。

New M1 Pro & M1 Max

Apple launched the new 14-inch and 16-inch MacBook Pro laptops at its recent October event. The new laptop features a new redesign with smaller bezels, a new screen, new ports, new Apple silicone, and more.

Performance (Processor, RAM, graphics)

The M1 Pro and M1 Max are the newest Apple System on a Chip (SoC), following the M1 that was released last year. I am not mentioning all the detail specs here as you can easily see at apple official website. Both of 14 and 16inches are in beast mode as they improve at all aspects, also more expensive.

Screen Display

The 14-inch and 16-inch MacBook Pros are the first Apple laptops to use a mini LED screen, which Apple calls the Liquid Retina XDR. The mini LED used in the 12.9-inch iPad Pro is a backlight technology with more LEDs than currently implemented. This gives you better backlight control, better image contrast, and greater dynamic range. These laptop displays are also the first displays to support a 120Hz refresh rate using ProMotion technology, previously found only on Apple’s iPhone and iPad Pro.

Design & Color

The new 14-inch and 16-inch MacBook Pro features a new aluminum case design that makes your notebook smaller than its predecessor. The bezel (the border around the screen) has been significantly reduced so that the MacBook Pro logo appears at the bottom of the laptop instead of at the bottom of the screen. At the top of the screen, like the iPhone, there’s a notch for the FaceTime camera. Apple creates the notch as deep as the menu bar so it doesn’t break into your workspace. The MacBook Pro is available in two colors, silver and space gray.

Ports

I am so glad the real ports are back, no extra dongles. The MacBook Pro comes with three Thunderbolt / USB 4 ports. Apple also includes an SDXC card slot, an HDMI 2.0 port, and a headphone jack that supports high-impedance headphones.

Power adapter & battery

The power adapter connects to the new MagSafe connector on your laptop. This is similar to the old MagSafe adapter for MacBooks pre-USB-C. However, the wattage of the adapter depends on the model you purchase. It can be said that the battery life has been dramatically improved. See more details on Apple’s official website.

No more touchbar

Apple introduced a touch bar in 2016 to replace function keys with a “brilliant Retina-quality multi-touch display,” but to say the least, it was a divisive feature. Apple seems to have been persuaded by users who don’t like the touchbar, as the touchbar has been added to the new M1 Pro MacBook Pro and replaced with function keys. These function keys are full size, not half height keys. Like previous MacBook Pro models, it has a Touch ID button in the upper right corner of the keyboard, but with a circular ring like the iMac keyboard. I personally like the solid function keys.

As a conclusion, the new macbook pros are really awesome, both in physical and performance. Apple listens the customers’ feedbacks and add back function keys, ports and other improvements as well. I expected the FaceID login as they are including big notch but not this time, may be next release I guess.

M1 (Pro, Max) 搭載 Mac Book Pro

グラフィック性能やメモリアクセス速度が強化された新型Mac Book Proが発表されました。

https://www.apple.com/jp/macbook-pro-14-and-16/

新しいMac Book ProはMac MiniやMac Book Airと同じM1シリーズを搭載していますが、
性能が引き上げられたM1 (Pro, Max)となっています。
M1 ProはM1と比較してGPUコアが2倍の16コア
M1 MaxはM1と比較してGPUコアが4倍の32コアとなっています。
また、メインメモリのアクセス速度も向上しています。

M1 Maxのグラフィック性能はPS5に近い性能のようですね。

高いグラフィック性能を活かしてゲーム用途に使おうとしても
M1に対応したゲームが現時点ではあまりありません。

ですので3Dモデルの作成や、4K、8Kで撮影した動画ファイルの編集用ですね。

中身だけではなく、外観にも変化があり
SDカードスロットやHDMI端子、充電端子としてMagsafeが追加されています。
キーボードもTouch Barが廃止されて物理ファンクションキーが復活しています。

発売日は10月26日です。
同日 macOS Monterey の配信も行われるようです。
