The number 69 has always been associated with sexual connotations for obvious reasons that we understand that it is not necessary to explain to anyone who has two fingers in the forehead. And it could be that Apple did not want to use this number in its applications.
This is indicated by a new theory from Apple fans that talks about Apple’s Weather app. According to them, citing The Verge, the app never reads 69º – Farenheit, of course, since at 69º Celsius we would be dead – and instead displays 70º.
As you can see in the images we attach below, a beta version of iOS 15 runs on the iPhone on the left, and the Weather app shows a temperature of 69 degrees. On the other hand, the iPhone on the right is running iOS 14.6 and a temperature of 70º appears. Both devices use the same location (Upper Nyack).
The possible interpretation that would explain everything
One of the possible reasons why the Weather app wouldn’t display the 69 degree figure would be that Apple may be converting temperatures from Celsius to Fahrenheit. This would have the effect of rounding the digits to another digit.
Assuming a comfortable city temperature of 20 degrees Celsius, converting to degrees Fahrenheit would cause the app to display at 68 degrees. However, if the temperature was 21 degrees Celsius, the conversion would be 69.8 degrees Fahrenheit
Another possible reason would be that there is a small bug in iOS 14.6 so that the temperature of 69 degrees is not displayed. But this is very unlikely, as it would be a very strange and too specific bug.
