The contingency table shows these very clearly, but I believe the question is about the future popularity table.
The future probability table shows that Swift is to the left of (smaller future probability) of Objective C. The coloring of the chart shows a much darker square for Swift -> Objective C than for Objective C -> Swift.
It seems surprising given your contingency table that your analysis would show that Objective C is going to be the more popular of the two.
if I understand it correctly that means that most people who move away from swift move to Objective C, but people moving away from Objective C also move to C# and Java.
Yes, this is correct. The second table shows conditional probabilities. Almost everyone moving from ObjC goes to Swift, but conversely out of the people moving from Swift it's more spread out
