Unsupported OS Version In Xcode

· · Leave a Comment

Last night I updated my iPhone OS to iOS 15. This morning I plugged my phone into my Macbook Air to work on an app but was unable to run the app on my phone because of the new operating system. The app is targeted to run on my iPhone under iOS Device the my phone’s iOS was listed as unsupported. Specifically Clint’s iPhone (unsupported OS version). This makes sense since I updated the iOS to version 15 but haven’t made any changes locally to support the new version of the software.

Here are the steps I took to get iOS 15 support for my Mac without updating Xcode or the OS.

  1. Open the DeviceSupport folder at Applications/xcode.app/contents/Developer/platform/iPhoneOS.platform/DeviceSupport
    1. Right click the Xcode app and select “Show Package Contents” to get into the XCode.app folder
  2. Download the DeviceSupport folder for iOS 15 (or any other iOS version you might be needing) and place inside the DeviceSupport folder alongside the other supported operating systems
  3. Clean Xcode build folder (Product -> Clean Build Folder)
  4. Delete the DerivedData folder at /Users/[user]/Library/Developer/Xcode/DerivedData
  5. Close Xcode
  6. Unplug and restart your phone
  7. After your phone has restarted, plug it back in and open Xcode. You should now be able to see your phone listed as a supported device with iOS 15.

Many thanks to these Stack Overflow and Apple Developer Forum posts for guiding me through the process.

Centralized Streaming Radio Stations

· · Leave a Comment

I listen to a lot of streaming radio stations during the day and wanted a way listen to each one on demand like a Spotify or Apple Music playlist, essentially a playlist for centralized streaming radio stations. Switching between a new browser tab every couple of hours isn’t an efficient way to stream, so I created a playlist file of indie rock in Seattle and Los Angeles, classical in New York and Switzerland and jazz in New Orleans and Newark and internet trance stations all into a nice collection.

To make it easy to go from station to station I created a radio.pls file that’s a collection of all my streaming radio stations in a single file. I can then open this file in VLC player which loads them all in a nicely organized playlist. When I find a new Internet radio station I like I’ll find the mp3 or stream source url and add it to this playlist file.

Here’s an example of what the playlist file source looks like and how to make a pls file for streaming sources.

Title1=KCRW (Eclectic Mix) - California listener powered radio

Title2=AH.FM - Internet Trance

Title3=UZIC - Internet Techno (Switzerland)

File4=https://kexp-mp3-128.streamguys1.com/kexp128.mp3
Title4=KEXP - Seattle listener powered radio

Here’s what the playlist looks like in the VLC player, too. This will also work with other player programs that are compatible with pls files – like Winamp.

Most COVID-19 Vaccinations By County & State

· · Leave a Comment

I was curious what counties and states are leading the way in COVID-19 vaccinations. I looked online and found a cool map from the NY Times but nothing that gave me a quick overview. So, I created this table to list the most COVID-19 vaccinations by county & state in order of the percentage vaccinated. This is the condensed version of the table, click here to view the full table. The full table lists the percent for everyone in the county as well as 12+/18+/65+ years old.

The data comes from a .JSON file from @mattwaite‘s GitHub repository. That data is updated daily from the API that powers the CDC COVID Data Tracker website.

From the CDC website, Completeness represents:

Percent of [state]s fully vaccinated recipients with valid county of residence. States with lower percentages for valid county of residence should be interpreted with caution.
