How to switch to another sim on the sims freeplay?

I change the clothes and when I switched back to game mood I clicked on the sim face on the corner. It works with me hope it works with yours too

You click the button above the sim's face. You can't do it until after the tutorial.

All you do is click on another SIM and when the box pop up on the top right you press the arrow and it will swap the Sims it worked for me I just had that challenge.

All you have to do is...
Click on one of your Sims who is not already selected
When you've done that, at the top it should say there name in the Bar...to the right of the bar click the button of the two Sims with arrows, as if they look like there switching
Hope this helped you

Step by step-
1- tap on the sim you want.
2- Look up to the name Bar. (Where it says you Sims name. E.g. Jules Conner)

3-On the left there should be a little green circle with a sort of back button on it, the one you click/tap to exit actions.
4- Look on the other side of the name, there should be another green circle with two faces and a arrow pointing (like a reverse arrow)
5-Tap on that.

I have added an image THAT IS NOT MINE as another example to try to help you.
